28-QFN USB 3.0 controller with I²C bus
The Microchip UPD350CT/Q8X is a USB controller with an I²C interface, supporting USB 3.0 protocol. It comes in a 28-VFQFN exposed-pad package (supplier device package 28-QFN, 4x4 mm).
The 4x4 mm footprint fits tight layouts where a larger QFP would not. CT works for prototypes or small-batch rework.
